    Assessment Guidance

    Guidance for achieving higher grades

    • 💡During practical assessments, narrate your actions to demonstrate understanding of why each step is performed.
    • 💡Always reference the relevant standard operating procedure or risk assessment when explaining decisions.
    • 💡Provide photographic or video evidence of before-and-after comparisons when evidencing corrective actions.
    • 💡Link equipment operation knowledge to quality control outcomes—show how your actions directly prevent defects.
    • 💡Always refer to the specific SOP (Standard Operating Procedure) for each machine during practical assignments; examiners award marks for strict adherence.
    • 💡For written components, clearly relate operational choices to quality outcomes—explain how adjustments prevent common defects like warping or cracking.
    • 💡Practice lock-out/tag-out procedures for maintenance scenarios; safety compliance is often a critical grading factor.
    • 💡Always reference the equipment manual and site-specific risk assessments in your answers
    • 💡Describe a step-by-step approach to operational tasks, highlighting checkpoints
    • 💡Show awareness of how your actions impact downstream processes and finished tile quality
    • 💡When recording evidence of competence, include clear before-and-after photos or video of machine setup and finished products, annotated with settings used.
    • 💡In written assessments, always reference the specific manufacturer’s manual or company SOP, and explain the rationale behind each step, especially safety points.
    • 💡For observation-based assessments, verbalise your actions as you work to demonstrate your understanding of why each step is important.
    • 💡Always highlight your ability to troubleshoot common issues, such as blade dulling or material misalignment, as this shows advanced operational knowledge.
    • 💡When completing written assessments or practical observations, always refer to the company's standard operating procedures (SOPs) and explain why each step is performed, not just how.
    • 💡In case study questions, identify the specific equipment parameters (e.g., ribbon speed, tin bath atmosphere) that would be adjusted to correct a described defect, and justify your reasoning.
    • 💡Photographic or video evidence of practical operation should clearly show you checking gauges, interpreting data, and making informed decisions—not just pressing buttons.
    • 💡When describing manufacturing processes, use precise technical terms like 'deflocculant' for slip preparation and 'pyrometric cones' for kiln temperature monitoring to demonstrate depth of knowledge.
    • 💡In exam answers, always link defects to their root causes (e.g., pinholes from organic matter in clay) and suggest practical remedies, showing you understand the production workflow.
    • 💡For high marks, discuss how modern automation (e.g., robotic glazing) impacts efficiency and consistency, but also acknowledge the continued importance of skilled hand-finishing for complex shapes.

    Common Mistakes

    Common errors to avoid in your coursework

    • Skipping pre-operation safety checks, leading to unguarded moving parts or undetected faults.
    • Overlooking material preparation steps, such as failing to stir slip before casting or using expired glaze.
    • Incorrectly setting process parameters (e.g., kiln temperature profile) resulting in product rejects.
    • Assuming equipment is functioning normally without monitoring, missing early signs of wear or blockage.
    • Students often neglect to verify machine guard interlocks before operation, leading to safety risks and non-compliance with assessment criteria.
    • A common error is misinterpreting gauge readings or failing to log production data, resulting in inconsistent product quality and loss of marks for documentation.
    • Learners frequently skip pre-operation checks, assuming equipment is set from previous shift, which can cause defects or breakdowns.
    • Bypassing safety interlocks or guards to save time
    • Failing to verify material specifications before loading
    • Neglecting to record minor stoppages or quality issues in shift reports
    • Using incorrect cleaning methods that could damage sensitive equipment
    • Failing to wear appropriate personal protective equipment (PPE) such as goggles, gloves, and hearing protection during machine operation.
    • Neglecting to check calibration and alignment before starting production, leading to poorly cut or uneven tiles.
    • Rushing or bypassing safety interlocks and guards, which can result in serious injury or machine damage.
    • Misinterpreting standard operating procedures, particularly when setting blade depth or pressure, causing excessive material breakage.
    • Learners often confuse the order of operations when warming up or cooling down the furnace or tin bath, leading to thermal stress and potential equipment damage.
    • Misinterpreting control system alarms as false positives without first checking process variables, which can result in uncorrected deviations and product defects.
    • Assuming that 'automatic' mode requires no monitoring; neglecting to verify sensor readings and machine performance can cause unnoticed drift from specifications.
    • Failing to link operational adjustments to downstream quality outcomes, e.g., not recognising that a slight change in annealing lehr temperature directly impacts glass stress and cutting accuracy.
    • Misconception: Sanitary ware is made from porcelain like fine china. Correction: While similar, sanitary ware typically uses vitreous china or fireclay, which have higher strength and lower water absorption for durability.
    • Misconception: Glaze is just a decorative coating. Correction: Glaze provides a non-porous, hygienic surface essential for sanitation; it also protects the ceramic body from staining and chemical damage.
    • Misconception: Firing is a single step. Correction: Sanitary ware undergoes two firings—biscuit firing to harden the clay, then glaze firing to melt the glaze—each with specific temperature profiles.
